5c307ba2a5 eal: register non-EAL threads as lcores
DPDK allows calling some part of its API from a non-EAL thread but this
has some limitations.
OVS (and other applications) has its own thread management but still
want to avoid such limitations by hacking RTE_PER_LCORE(_lcore_id) and
faking EAL threads potentially unknown of some DPDK component.

Introduce a new API to register non-EAL thread and associate them to a
free lcore with a new NON_EAL role.
This role denotes lcores that do not run DPDK mainloop and as such
prevents use of rte_eal_wait_lcore() and consorts.

Multiprocess is not supported as the need for cohabitation with this new
feature is unclear at the moment.

264f7f80e1 eal/arm: adjust memory barriers for IO on ARMv8
Change the barrier APIs for IO to reflect that Armv8-a is other-multi-copy
atomicity memory model.

Armv8-a memory model has been strengthened to require
other-multi-copy atomicity. This property requires memory accesses
from an observer to become visible to all other observers
simultaneously [3]. This means

a) A write arriving at an endpoint shared between multiple CPUs is
   visible to all CPUs
b) A write that is visible to all CPUs is also visible to all other
   observers in the shareability domain

This allows for using cheaper DMB instructions in the place of DSB
for devices that are visible to all CPUs (i.e. devices that DPDK
caters to).

Please refer to [1], [2] and [3] for more information.

598be72395 vfio: support VF token
The Linux kernel module vfio-pci introduces the VF token to enable
SR-IOV support since 5.7.

The VF token can be set by a vfio-pci based PF driver and must be known
by the vfio-pci based VF driver in order to gain access to the device.

Since the vfio-pci module uses the VF token as internal data to provide
the collaboration between SR-IOV PF and VFs, so DPDK can use the same
VF token for all PF devices by specifying the related EAL option.

bab9497ef7 regexdev: introduce API
As RegEx usage become more used by DPDK applications, for example:
* Next Generation Firewalls (NGFW)
* Deep Packet and Flow Inspection (DPI)
* Intrusion Prevention Systems (IPS)
* DDoS Mitigation
* Network Monitoring
* Data Loss Prevention (DLP)
* Smart NICs
* Grammar based content processing
* URL, spam and adware filtering
* Advanced auditing and policing of user/application security policies
* Financial data mining - parsing of streamed financial feeds
* Application recognition.
* Dmemory introspection.
* Natural Language Processing (NLP)
* Sentiment Analysis.
* Big data database acceleration.
* Computational storage.

Number of PMD providers started to work on HW implementation,
along side with SW implementations.

This lib adds the support for those kind of devices.

The RegEx Device API is composed of two parts:
- The application-oriented RegEx API that includes functions to setup
  a RegEx device (configure it, setup its queue pairs and start it),
  update the rule database and so on.

- The driver-oriented RegEx API that exports a function allowing
  a RegEx poll Mode Driver (PMD) to simultaneously register itself as
  a RegEx device driver.

RegEx: A regular expression is a concise and flexible means for matching
strings of text, such as particular characters, words, or patterns of
characters. A common abbreviation for this is â~@~\RegExâ~@~].

RegEx device: A hardware or software-based implementation of RegEx
device API for PCRE based pattern matching syntax and semantics.

PCRE RegEx syntax and semantics specification:
http://regexkit.sourceforge.net/Documentation/pcre/pcrepattern.html

RegEx queue pair: Each RegEx device should have one or more queue pair to
transmit a burst of pattern matching request and receive a burst of
receive the pattern matching response. The pattern matching
request/response embedded in *rte_regex_ops* structure.

Rule: A pattern matching rule expressed in PCRE RegEx syntax along with
Match ID and Group ID to identify the rule upon the match.

Rule database: The RegEx device accepts regular expressions and converts
them into a compiled rule database that can then be used to scan data.
Compilation allows the device to analyze the given pattern(s) and
pre-determine how to scan for these patterns in an optimized fashion that
would be far too expensive to compute at run-time. A rule database
contains a set of rules that compiled in device specific binary form.

Match ID or Rule ID: A unique identifier provided at the time of rule
creation for the application to identify the rule upon match.

Group ID: Group of rules can be grouped under one group ID to enable
rule isolation and effective pattern matching. A unique group identifier
provided at the time of rule creation for the application to identify
the rule upon match.

Scan: A pattern matching request through *enqueue* API.

It may possible that a given RegEx device may not support all the
features
of PCRE. The application may probe unsupported features through
struct rte_regexdev_info::pcre_unsup_flags

By default, all the functions of the RegEx Device API exported by a PMD
are lock-free functions which assume to not be invoked in parallel on
different logical cores to work on the same target object. For instance,
the dequeue function of a PMD cannot be invoked in parallel on two logical
cores to operates on same RegEx queue pair. Of course, this function
can be invoked in parallel by different logical core on different queue
pair. It is the responsibility of the upper level application to
enforce this rule.

In all functions of the RegEx API, the RegEx device is
designated by an integer >= 0 named the device identifier *dev_id*

At the RegEx driver level, RegEx devices are represented by a generic
data structure of type *rte_regexdev*.
RegEx devices are dynamically registered during the PCI/SoC device
probing phase performed at EAL initialization time.
When a RegEx device is being probed, a *rte_regexdev* structure and
a new device identifier are allocated for that device. Then, the
regexdev_init() function supplied by the RegEx driver matching the
probed device is invoked to properly initialize the device.

The role of the device init function consists of resetting the hardware
or software RegEx driver implementations.

If the device init operation is successful, the correspondence between
the device identifier assigned to the new device and its associated
*rte_regexdev* structure is effectively registered.
Otherwise, both the *rte_regexdev* structure and the device identifier
are freed.

The functions exported by the application RegEx API to setup a device
designated by its device identifier must be invoked in the following
order:
    - rte_regexdev_configure()
    - rte_regexdev_queue_pair_setup()
    - rte_regexdev_start()

Then, the application can invoke, in any order, the functions
exported by the RegEx API to enqueue pattern matching job, dequeue
pattern matching response, get the stats, update the rule database,
get/set device attributes and so on

If the application wants to change the configuration (i.e. call
rte_regexdev_configure() or rte_regexdev_queue_pair_setup()), it must
call rte_regexdev_stop() first to stop the device and then do the
reconfiguration before calling rte_regexdev_start() again. The enqueue and
dequeue functions should not be invoked when the device is stopped.

Finally, an application can close a RegEx device by invoking the
rte_regexdev_close() function.

Each function of the application RegEx API invokes a specific function
of the PMD that controls the target device designated by its device
identifier.

For this purpose, all device-specific functions of a RegEx driver are
supplied through a set of pointers contained in a generic structure of
type *regexdev_ops*.
The address of the *regexdev_ops* structure is stored in the
*rte_regexdev* structure by the device init function of the RegEx driver,
which is invoked during the PCI/SoC device probing phase, as explained
earlier.

In other words, each function of the RegEx API simply retrieves the
*rte_regexdev* structure associated with the device identifier and
performs an indirect invocation of the corresponding driver function
supplied in the *regexdev_ops* structure of the *rte_regexdev*
structure.

For performance reasons, the address of the fast-path functions of the
RegEx driver is not contained in the *regexdev_ops* structure.
Instead, they are directly stored at the beginning of the *rte_regexdev*
structure to avoid an extra indirect memory access during their
invocation.

RTE RegEx device drivers do not use interrupts for enqueue or dequeue
operation. Instead, RegEx drivers export Poll-Mode enqueue and dequeue
functions to applications.

The *enqueue* operation submits a burst of RegEx pattern matching
request to the RegEx device and the *dequeue* operation gets a burst of
pattern matching response for the ones submitted through *enqueue*
operation.

Typical application utilisation of the RegEx device API will follow the
following programming flow.

- rte_regexdev_configure()
- rte_regexdev_queue_pair_setup()
- rte_regexdev_rule_db_update() Needs to invoke if precompiled rule
  database not
  provided in rte_regexdev_config::rule_db for rte_regexdev_configure()
  and/or application needs to update rule database.
- rte_regexdev_rule_db_compile_activate() Needs to invoke if
  rte_regexdev_rule_db_update function was used.
- Create or reuse exiting mempool for *rte_regex_ops* objects.
- rte_regexdev_start()
- rte_regexdev_enqueue_burst()
- rte_regexdev_dequeue_burst()

fa19eb20d2 examples/l2fwd: add forwarding port mapping option
Current l2fwd application statically configures adjacent ports as
destination ports for forwarding the traffic.

Add a portmap option to pass the forwarding port pair mapping which allows
the user to configure forwarding port mapping.

If no portmap argument is specified, destination port map is not
changed and traffic gets forwarded with existing mapping.

To align port/queue configuration of each lcore with destination port
map, port/queue configuration of each lcore gets modified when portmap
option is specified.

Ex: ./l2fwd -c 0xff -- -p 0x3f -q 2 --portmap="(0,3)(1,4)(2,5)"

With above portmap option, traffic received from portid = 0 gets forwarded
to port = 3 and vice versa, similarly traffic gets forwarded on other port
pairs (1,4) and (2,5)

c12f4f217d app/flow-perf: add deletion rate calculation
Add the ability to test deletion rate for flow performance
application.

This feature is disabled by default, and can be enabled by
add "--deletion-rate" in the application command line options.

bf3688f1e8 app/flow-perf: add insertion rate calculation
Add insertion rate calculation feature into flow
performance application.

The application now provide the ability to test
insertion rate of specific rte_flow rule, by
stressing it to the NIC, and calculate the
insertion rate.

The application offers some options in the command
line, to configure which rule to apply.

After that the application will start producing
rules with same pattern but increasing the outer IP
source address by 1 each time, thus it will give
different flow each time, and all other items will
have open masks.

The current design have single core insertion rate.

c79a1c6746 bus/pci: optimize bus scan
In order to optimize the PCI management, RTE_KDRV_NONE based
device driver probing removed by not adding them to list in
the scan phase.

The legacy virtio is the only consumer of RTE_KDRV_NONE based device
driver probe scheme. The legacy virtio support will be available
through the existing VFIO/UIO based kernel driver scheme.

This patch also removes the deprecation notice for the same.

b901d92836 bpf: support packet data load instructions
To fill the gap with linux kernel eBPF implementation,
add support for two non-generic instructions:
(BPF_ABS | <size> | BPF_LD) and (BPF_IND | <size> | BPF_LD)
which are used to access packet data.
These instructions can only be used when BPF context is a pointer
to 'struct rte_mbuf' (i.e: RTE_BPF_ARG_PTR_MBUF type).

a7d42145cc net/pcap: support Tx nanosecond timestamps
When capturing packets into a PCAP file, DPDK currently uses
microseconds for the timestamps. But libpcap supports interpreting
tv_usec as nanoseconds depending on the file timestamp precision,
as of commit ba89e4a18e8b ("Make timestamps precision configurable").

To support this, use PCAP_TSTAMP_PRECISION_NANO when creating the
empty PCAP file as specified by PCAP_OPEN_DEAD(3PCAP) and implement
nanosecond timeval addition. This also ensures that the precision
reported by capinfos is nanoseconds (9).

Note that NSEC_PER_SEC is defined as 1000000000L instead of 1e9 since
the latter might be interpreted as floating point.

67a661ed85 eal: replace page sizes enum with a set of constants
Clang on Windows follows MS ABI where enum values are limited to 2^31-1.
Enum rte_page_sizes has members valued above this limit, which get
wrapped to zero, resulting in compilation error (duplicate values in
enum). Using MS ABI is mandatory for Windows EAL to call Win32 APIs.

Remove rte_page_sizes and replace its values with #define's.
This enumeration is not used in public API, so there's no ABI breakage.
Announce API changes for 20.08 in documentation.

a1da6f624c net/mlx5: add reclaim memory mode
Currently, when flow destroyed, some memory resources may still be kept
as cached to help next time create flow more efficiently.

Some system may need the resources to be more flexible with flow create
and destroy.  After peak time, with millions of flows destroyed, the
system would prefer the resources to be reclaimed completely, no cache
is needed. Then the resources can be allocated and used by other
components. The system is not so sensitive about the flow insertion
rate, but more care about the resources.

Both DPDK mlx5 PMD driver and the low level component rdma-core have
provided the flow resources to be configured cached or not, but there is
no APIs or parameters exposed to user to configure the flow resources
cache mode. In this case, introduce a new PMD devarg to let user
configure the flow resources cache mode will be helpful.

This commit is to add a new "reclaim_mem_mode" to help user configure if
the destroyed flows' cache resources should be kept or not.

Their will be three mode can be chosen:
1. 0(none). It means the flow resources will be cached as usual. The
resources will be cached, helpful with flow insertion rate.
2. 1(light). It will only enable the DPDK PMD level resources reclaim.
3. 2(aggressive). Both DPDK PMD level and rdma-core low level will be
configured as reclaimed mode.

With these three mode, user can configure the resources cache mode with
different levels.

1adbb6421a doc: announce splitting ethdev ops struct
For the ABI compatibility it is better to hide internal data structures
from the application as much as possible. But because of some inline
functions 'struct eth_dev_ops' can't be hidden completely.

Plan is to split the 'struct eth_dev_ops' into two as ones used by
inline functions and ones not used, and hide the second part that not
used by inline functions completely to the application.

Because of ABI break the work will be done in 20.11
